Sharing Google Plus postings to other social media sites

I was sharing a listing on my Etsy shop to google+. Usually, I get the link of the Google +post right after posting, without a problem. Goggle asks if I need to s=view the post.
Today, I posted the link and it didn't offer to view the posting.
So, I went to my page.  It is with a lot of postings. Each posting has a time of posting shown on top of it. When I clicked on it, it opened on another page. I saw the page has a url on the address bar and only the one posting at that particular time is visible. So I copied the url and posted it on other social media sites. It works .
Want to see what I shated in the morning?
